AI Technical Summary

Benefits of technology

The present invention aims to provide a lawn mower with a flap mechanism in the cutter blade without compromising on its weight distribution balance. The technical effect of this invention is that it allows for the inclusion of a flap mechanism without affecting the stability and balance of the mower.

Problems solved by technology

However, when the motor having a heavy weight is provided at a position away from the blade rotation axis in the front / rear direction, a suitable balance of weight distribution is lost, and the lawn mower cannot be handled by the user easily.
For example, in the case where the motor is provided at a position away from the blade rotation axis in the front direction, at the time of floating the front wheels above the ground to change the orientation of the lawn mower, the load required for depressing the control handle becomes large, and the user's burden becomes large.
In contrast, in the case where the motor is provided at a position away from the blade rotation axis in the rear direction, at the time of operating the lawn mower in the slope area (uphill slope), the front wheels tend to float above the ground, and the user cannot operate the lawn mower accurately.

Abstract

A lawn mower includes a cutter blade having flaps and a flap drive mechanism. The flap drive mechanism includes a flap drive source and an intermediate power transmission unit. The intermediate power transmission unit is provided on a power transmission path between the flap drive source and the flaps and provided coaxially with a blade rotation axis. An output axis of a motor is provided coaxially with a blade rotation axis and the intermediate power transmission unit.

Description

TECHNICAL FIELD[0001]The present invention relates to a lawn mower (lawnmower) including a cutter blade having a flap with a flap angle being changeable.BACKGROUND ART[0002]A rotary lawn mower cuts (clips) grass on lawns by rotating a cutter blade accommodated in a housing having an opened bottom, along the grass. Such a lawn mower is, for example, disclosed in the specification of U.S. Pat. No. 7,275,355. According the specification of U.S. Pat. No. 7,275,355, the grass (clippings) cut by a cutter blade is swirled and lifted upward in a housing by an air lift unit and then stored in a clippings container. A motor for driving rotation of the cutter blade is provided coaxially with a blade rotation axis.SUMMARY OF INVENTION[0003]In this regard, in order to efficiently generate transportation wind (swirl wind) for swirling grass clippings in the housing and transporting the grass clippings into the grass clippings container, it may be considered to provide a flap having a changeable f...
